关于matlab中矩阵左除和右除

%if expression is A * C = B,we want to get C

A = [1,3,3;3,1,1;] % 2*3

B = [1,3,3;] %3*1

C = B/A %means inv(A)* B , change to (3*2) *(2*1) = 3*1

A1 =[0,1;-1,-1;1,1]

B1 =[1;1;1]

C1 = B1\A1 %as normal

From the case.We know a and c if a * c = b in  correct dimensions,we use\, or if need to get inv(a), use /
